12 Chapter 1 Product Description 1 Product Description 1.1 Function Description The Loop-AM 3440 is an Access Multiplexer that can combine various digital access interfaces into multiple E1 or T1 lines for convenient transport and switching. Interfaces include HDSL, U type used in ISDN, RS232, E&M, and V.35. These interfaces are compatible with other Loop products such as the Loop-H 3900 for HDSL and Loop-U 3500 for U. Using these products, a DTE interface can be extended over copper wire pairs. Up to as many n x 64 Kbps interfaces are then multiplexed to fill an E1 or T1 line, with full flexibility of time slot assignment. The Loop-AM 3440 supports management through a VT100 console port as well as Ethernet, SLIP, Telnet, and SNMP, so that it can be controlled and diagnosed from remote locations as well as on site. Optional inband management channel and LoopView with GUI are available. There are multiple status LEDs which can assist in on-site diagnoses. The Loop- AM 3440 features extensive diagnostics menus to assist installers and operators in troubleshooting line problems should they occur. On both the E1/T1 network side and customer U interface side, the Loop- AM 3440 offers local loopback, payload loopback, and line loopback. The Loop- AM 3440 also provides remote loopback capabilities so that a single operator can diagnose both the E1/T1 line and the U-interface line. Loop-AM has a built-in BERT that generates test pattern and detects pattern errors. 1.2 Physical Description Although it can be used as a desk-top unit, the Loop-AM 3440 is designed for rack mounting. Typically this unit is to be installed in a Central Office location and is available with a single or dual 48 Vdc power supply. The front of the unit can accept 4 E1/T1 interfaces and multiple U/ V.35/ HDSL/ RS232 interface lines. In addition a SLIP port is provided for connection to TELNET, Ethernet, or Inband management. Also featured is a console port for connection to a VT-100 terminal. The rear of the unit is blank except for DC fan connectors which will supply power to an external fan tray, if warranted. 1-1

37 Chapter 3 Operation 3 Operation Using a VT100 terminal, the Loop-AM provides a comprehensive user interface. The Loop-AM uses out-ofband link within the U-interface to communicate to the matching remote Loop-AM unit so that an operator from one side can obtain information on both sides of the U-interface line. The configuration changes on one side can be viewed from the other side. Note: With the Loop-AM 3440 at one end, the Loop-AM 3440 must be, by default, configured as LT. The remote Loop-AM unit, when connected to the Loop-AM 3440 must be configured as NT. Loop-AM also uses out-of-band link within the E1 interface to communicate to the matching Loop-AM at the far end of the E1 network so that an operator from one side can obtain information on both sides of the E1 network. The configuration changes on one side can be viewed from the other side. The E1 channel assignment changes can be sent to the remote unit when the link between two units is up. Through use of FDL data link, the remote unit updates its configuration accordingly upon receipt of the new configuration. 3.1 Quick Start for Loop-AM After installation, the user may want to familiarize himself with the equipment immediately. The following abbreviated instructions will give the user a quick start Power On Turn power on by attaching a power cable to the front of the unit Return to Default Setting The unit is shipped with factory default setting Using Front Panel There is no front panel on the Loop-AM3440. A hand-held LCD device, which will take the place of a front panel, is currently under development. This device will allow configuration of and access to the various features without the need of a VT100 terminal. Please stay in contact with your Loop vendor for availability of this device Review of Default Settings All the default settings can be reviewed or changed. This is done by selecting the menu item. Either a submenu is shown or the selected setting is indicated with an asterisk Map Setup Connect a VT100 terminal to the Console port. Press <o> to logon, then press <s> for system setup. Move the cursor to MAP and press <Enter>. To change the settings, use arrow keys to select time slot. Press <Tab> to change the port values and enter numbers for the time slot. Press <Esc> to exit the TSI map DS1 Next, adjust the DS1 settings Unit Selection To review or change U-port or HDSL settings, press <u> from the main menu. 3-1

38 Chapter 3 Operation Using Terminal To use the RS232 interface to configure the unit, connect a VT-100 terminal to the CONSOLE/SLIP (button down/ button up) connector using a null modem cable. The VT-100 terminal can be a PC running a VT-100 emulator software. The unit is configured as a DTE. Thus a null modem is needed for direct connection to a VT-100. Upon connection, press ENTER and ESC alternately to bring the main menu into view. Press O (Log On) to see the full menu. Press S (System Setup) to review or change the configuration Unit Status The first screen on the terminal has a line on U-PORT/ HDSL-PORT Status. For each of the plug-in slots, an I means that the unit is in place. S means SYNC Review of Default Settings The entire configuration is shown when S is pressed. To change any setting, use the arrow keys to move to the target setting. Then press the TAB key repeatedly to cycle to the desired setting for any selected parameter. 3.2 System Operation Date Loop-AM is equipped with a RTC (Real Time Clock). User can change the current date and time as necessary. To save RTC battery life, the RTC is activated by the manufacturer just before shipping. The RTC battery has a 10 years power-off life cycle Master Clock This product has a system clock PLL (Phase Lock Loop) which may be phase locked to the DS1 line clock or internal clock. The default master is the DS1 line clock. NOTE: If no DS1 line clock is available, Loop-AM will automatically switch to the internal clock source. Loop-AM will automatically switch back to the DS1 line clock when card plug-in Console Port The console port allows the user either to use a local VT-100 terminal via null-modem connection or use a remote VT-100 terminal via modem for system configuration, diagnostics, polling status reports, etc. The console port baud, data bit length, stop bit length, parity bit length, XON-XOFF flow control, and interface type are as shown below. 3-2

It also can be used to change system configurations and clear the alarm queue, etc. By enabling the menu-lock, only read operations are allowed. Modifications to the current status are not allowed. Users may not change system configurations or clear performance data.! Password and menu-clock options are disabled by default! The default password is LOOP Logon, Logoff, and Password Logoff prevents system configuration changes at the terminal, while logon allows system configuration changes. The password feature is used to augment lock control against unauthorized terminal users from changing system parameters from the terminal. With password enabled, logon requires entering the correct password. If password is disabled, no password is required to logon.! The default option of the password is disabled.! The default password is LOOP. If password is enabled, users must enter the password when logging in to gain the privilege to change system configurations by the terminal. To change the password for the first time, enter the default password when prompted for the old password. 3.3 DS0 Channel Map DS0 channel multiplexing is done by the MAP command. A map contains 31 DS0 channels (E1) or 24 DS0 channel (T1) where a single DS0 channel can be assigned to the B1 or B2 channel of any U-PORT or n x 64 Kbps HDSL port. If in-band management is need, select 1 DS0 channel map to SNMP. An idle code is transmitted on all unused channels. NOTE: For E1 network interface with HDB3 coding or T1 network interface with B8ZS coding all remote DTE ports with 56 Kbps, all channels are available for any DS0 assignment, data or voice. However, for either network interface with AMI coding, user should assign only alternate odd or even DS0 channels for 64 Kbps data. This is to guarantee one's density requirement. 3.4 DS1 Network Line Configuration A detailed option list of E1 line configuration is in Table 3-2. The following paragraphs will describe each item Frame Format For the E1 line interface, the frame format is ITU G.704. Either 2-frame, or 16-frame structure can be selected. Only the 16-frame provides CRC and optional CAS. For the T1 line interface, either D4 or ESF frame format is 3-3

40 Chapter 3 Operation available. In ESF frame format mode, user can choose either AT&T or ANSI facility data link protocol. ESF & T1.403 chooses ANSI ESF data link protocol and one second performance report will be sent to the network every second automatically. Also, ANSI and AT&T data link message is acceptable in ANSI ESF frame format mode. However, AT&T ESF frame format mode only accept AT&T ESF data link protocol Line Code For the T1 line interface, either AMI (Alternate Mark Inverting) or B8ZS (bipolar with 8 zero substitution) line code format can be chosen. For thee1 line interface, either AMI (Alternate Mark Inverting) or HDB3 (high density bipolar of length 3) line code format can be chosen. Be sure the line code chosen matches that used on the network Interface The T1 interface can be long haul or short haul. Long haul has higher powered output to drive long lines, while short haul is more appropriate for intraoffice connections. E1 interface will only display 120 Ohm twisted pair or 75 Ohm coaxial cable, which is a jumper choice Facility Data Link Whereas for T1, the FDL (facility data link) is part of the ESF structure, for E1, this is not part of the standard. Loop-AM 3440 uses a proprietary FDL within the E1 frame structure to facilitate remote control and remote performance and statistics monitoring. This FDL, for E1 only, can be turned ON or OFF. For E1, user can set Sa-bit (Sa4-Sa8) to select FDL channel Equalization (Line Build-Out) For the T1 line long haul interface, the transmit LBO (line build-out) can be programmed to either 0 db, -7.5 db, or -15 db. For the T1 line short haul interface, the equalization can be set to equivalent cable distances up to 655 feet Equalization Whether long haul or short haul, for T1, further refinements of the output signal can be made using the EQU controls. For long haul, the choices are in db of inserted loss. For short haul, the choices are in equivalent distances of inserted loss AIS AIS, alarm indication signal, notifies the far end that an alarm condition or a loopback and diagnostic test are in progress. Thus customer signals are blocked. The AIS can be sent two ways. In the framed mode, all time slots will have all ones sent but the framing pattern will be preserved. In the unframed mode, all ones are sent for all time slots RAI (Remote Alarm Indication) Loop-AM transmits RAI (Remote Alarm Indication) when it detects LOS (Loss of Signal), AIS (Alarm Indication Signal), or OOF (Out of Frame) for 2.5 ± 0.5 seconds. User can disable this feature by disable RAI (Remote Alarm Indication) command CRC (Cycle Redundancy Check) Format Loop-AM can be used in two frame or multiframe mode. For two frame mode, set CRC to OFF. For multiframe mode, set CRC to ON. A proprietary facility data link is implemented in both modes to facilitate remote system control and performance and statistics monitoring. 3-4

41 Chapter 3 Operation In-Band Signaling In all cases, Loop-AM utilizes a proprietary facility data link, FDL for E1, or in-band signaling for T1, to achieve remote system control and performance and statistics monitoring Idle Code Any DS0 channel which is not assigned to any U-PORT is an idle channel. An idle code is transmitted on idle DS0 channel. User may program the idle channel to any bit pattern from 0x00 to 0xFF. Note: Due to one's density requirement, it is advised that idle code to be set as 0xD5. Or, user must program idle code to contain at least two bits of '1'. The factory default idle code is 0xD5.

Another two settings for Loop-AM operation, mode and link, are also important, but must be locally set. The following paragraphs describe each, which is also summarized in Table Channel When a DTE port is configured to run at 64 Kbps or above, the channel to associate with the DTE port can be either B1 or B2. Else it must be B1+B2. IDLE means no channel is assigned, which applies only if the speed is 0, or idle 3-5
